BERNARD BIRD, OF BUFFALO, NEW YORK.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 352,511, dated November16, 1886.

Application filed February 10, 1886. Serial No. 191,389. (No model.)

To all whom it may concern:

Be it known that I, BERNARD BIRD, of Buffalo, in the county of Erie andState of New York, have invented certain new and useful Improvements inCar Couplings; and I do hereby declare that the following description ofmy said invention, taken in connection with the accompanying sheet ofdrawings, forms a full, clear, and exact specification, which willenable others skilled in the art to which it appertains to make and usethe same.

My present invention has general reference to improvements incar-couplings; and it consists, essentially, in the novel and peculiarcombination of parts and details of construction, as hereinafter firstfully set forth and described, and then pointed out in the claim.

In the drawings already mentioned, which serve to illustrate my saidinvention more fully, Figure l is a side elevation of a pair ofdraw-heads coupled together, the one at the right hand being shownaffixed to a fragment of a car and supplied with an uncoupling device.Fig. 2 is a longitudinal sectional elevation, and Fig. 3 a plan of adraw-head Figs. 4 and 5 are end elevations of the draw-heads.

Like parts are designated by corresponding letters of reference in allthe figures.

This invention embodies improvements upon the device for which LettersPatent of the United States were granted to me September 23, 1884, No.305,418, the object being to provide for means for carrying a link andpin with each draw-head, so as to prevent the possibility of twodraw-heads meeting without a coupling link or pin to make connection,and

also in a novel device for upholding the link within the draw-headduring the time that connection is being made.

The principal features of my car-coupling are the same as those of thedevice described and claimed in the Letters Patent heretofore recited,viz:

A is the draw-head, having on one side and nearits forward end two lugs,A,within which is pivoted, by the bolt a, Fig. l, a link, F, to which issecured a second link, G, the latter being an intermediary between saidlink F and the coupling-link proper, B, as clearly shown in thedrawings, whereby the last-mentioned link is permanently secured to thedraw-head, and always ready to be used in coupling whenever occasionrequires.

O is the coupling-pin. It is vertically movable within the pin-aperture0, Fig. 2, of the draw-head, but prevented from being removed therefromby a pin, 0, striking against a shoulder, b, in said aperture, therebeing two grooves, g g, in the aperture 0 for the passage of said pin 0.pin-aperture O is an offset, 6, Fig. 5, upon which the pin G,when pulledup as far as possible, may rest, to prevent coupling, which is verydesirable in many cases. I

Behind the coupling-pin there is in th draw-head a rise, D, terminatingin a cylindrical projection, D, there being located within saidprojection D a bolt, E, having its head acted upon by a spiral spring,E, for the purpose hereinal'ter'to be referred to. In the sides of theprojection D are oppositely-located slots d, through which passes abolt, d, carrying the dog H, which dog sustains the pin 0 prior tocoupling, and upholdsthe link, substantially as described in the patentalready mentioned, except that the head of the bolt E, pressing upon thedog H by the spiral spring E, sustains said link B in asubstantially-horizontal position, the action being assisted by atailpiece or counterpoise, I, Fig. 2, operating in the passage J,running longitudinally through the said draw-head, said counterpoisebeing pivoted to the dog at h. v

To the face of the car-body O is secured a hand-rod,N,havingcentrallyabell-crank,Mm, said rod being j ournaled in properly-arrangedbearings, readily understood. Above this hand-rod, in the middle of thecar above the draw-head, is pivoted a lever, L, to which thecoupling-pin O is attach ed by means of a chain, K. Depressing thehand-rod N causes the bell-crank M to lift the lever L, and this in turnto pull the pin upward, thus uncoupling a pair of draw-heads in theeasiest possible manner.

The operation of the cars in coupling does not differ materially fromthat described in my Patent No. 305,418, and a description thereof istherefore deemed superfluous.

In the upper part of the ICQ Having thus fully described my invention,In testimony that I claim the foregoing as 10 I claim as new and desireto secure to me by my invention I have hereto set my hand in LettersPatent of the United States the presence of two subscribing witnesses;

The combination, with the draw-head and 5 coupling-link, of the pivoteddog H, bolt E, BERNARD BIRD.

with spiral spring E, and the eonnterpoise I, pivoted to said dog andarranged to operate Witnesses: Within the passage J as and for thepurpose MICHAEL J. STARK, set forth. JESSIE A. TULLEY;
